I .105 will now be described in detail are prefer- In assembling the crystals vor lenses into the present goggle construction, theguards are first removed so as to allow the crystals to be slipped into place through the openings 19. Each guard is then arranged adjacent to its how 11, and thereafter the clip 20 is snapped into place. When the parts have thus been operatively engaged, the two ends of the bow will abut the ends of the opening 19, its intermediate curved portion conforming generally tothat of the crystal. When the clip 20 is applied in place by snapping its ends 21 into locking relation with the slits or cuts 14:, the guard is locked immovably to the frame. This same looking relation serves also to prevent move-- ment of the crystal within the guard. It is obvious that a withdrawal of the crystal from theguard may beeffected by a reversal of the operations described.

I will now describe the construction shown particularly in Figs. 6 to 10 inclusive. In this case a frame is employed consisting of two parts each in the form of a bow or eye 22 having a bridge piece 23 that is adapted to co-operate with the bridge piece of the other when resting on the nose of the wearer. The two parts of the frame are shown as flexibly connected together by means of a strap 24;. According to the present construction each bow is arranged to extend around the edge of a crystal or lens for 180 degrees or less, and is provided near one of its ends with a notch 25 on the inner side and near the opposite end with a slit 26 on its outer side.

The mountings of the lenses or crystals in this goggle is so arranged and constructed as to permit them to be readily attached or detached relative thereto, and to hold them immovably in place thereon. F or this pur-' pose I employ a guard 27 of suitable form and shape to exclude light and particles from the eyes of the wearer and provided with a cylindrical portion 28 which is suitably channeled as at 29 to hold in place a crystal or lens 30. As a means of entry or withdrawal of the crystal an elongated opening 31 is arranged in the guard in line with the channel 29 having a length substantially the same as the arc of the bow 22 so that in assembled relation the ends thereof may rest adjacent to the ends of the opening 31. A second and shorter opening 32 slightly spaced from the elongated opening 31 and separated therefrom by a web 33 is arranged toreceive the end of the bow adjacent to the notch 25 which constitutes in effect a hook adapted to co-operate with the opening 32. By this arrangement a connection is established between the guard and frame at one end of the bow. On the opposite end of the bow another connection is provided consisting of a spring 34L secured to the guard at one end as at 35 and having its opposite end turned as at 36 to provide as described.

ea er? a catch 37 which is adapted to the cut or slit 26. The tendency of the spring is always to snap towards the bow, sothat when the parts are assembled in the manner described, the catch of the spring will automatically enter into locking relation with the proximate end of the bow to hold the guard immovably in the frame and of the crystal within to prevent movement the guard. It is obvious that a withdrawal of the crystal from the guard may be effected by the reversal of the operations described. i

The two forms of goggle illustrated and which have now been described in detail are simple in their construction and render facile a substitution of crystals or lenses whenever this may be desired. In addition these constructions securely hold the crystale in place, and prevent the entrance of particles of dust and the likearound them. Obviously the invention is susceptible of embodiment in other forms than the ones herein suggested, and in respect of any changes or modifications that may utilize the principles of this invention, as described in the claims below, I desire that they should be included within the scope of this patent.

This application is a division of my cooperate with I pending application for Letters Patent'of No. 323,990, filed by edge of contour suitable to seat against the face of the wearer and each having near its outer edge an annular interior groove for the accommodation of the edge of a crystal. there being a semicircular slot at the inner side of each said groove giving accessthereto and permitting'the introduction or removal of the crystal, a crystal seated within each said groove, a semicircular frame adjacent to each said slot and having its end portions adjacent and having a'locking slit at the end of one said end portion, and spring means on the eye guard and engaging the slit of the frame to thereby hold the frame in position adjacent to the guard whereby the frame and guard may be engaged and disengaged by fiexion of the spring means and without necessary flexion of the frame, substantially 2. A pair of goggles comprising in combination two eye guards each having its inner edge of contour suitable to seat against the face of the wearer and each having near its outer edge an annular interior groove for the accommodation of the edge of a crystal, there being a semi-circular slot at the inner side of each said groove giving access thereto and permittlng the introduction or reto the ends ofthe slot, 7

moval of the crystal, a crystal seated within each said groove, a semi-circular frame closing each said slot and having its end portions adjacent to the ends of the slot there being a locking slit in the end portion of one end of each said frame, and a spring on the guard adjacent to said end of the frame, and adapted to engage the slit of the frame whereby the frame and guard may be engaged and disengaged by flexion 10 of the spring means and ithout necessary fiexion of the frame, substantially as described.
